Embodiment 2
[0036] According to the formula in Example 1, this example provides a preparation method of a nutritional fortifier for laying hens, which specifically includes the following steps: Weigh each component by weight, and add them to the mixer in order from large to small by weight In the middle, after mixing evenly, use non-toxic bags to pack, that is.
Embodiment 3
[0038] Feeding effect test of nutrient fortifiers for laying hens.
[0039] According to each formulation in Example 1, according to the preparation method of Example 2, 8 groups of laying hen nutritional fortifiers were prepared.
[0040] Select 12000 Roman pink layer hens of the same age (16 weeks of age, not opened production), adopt single factor complete randomized experimental design, be divided into 9 treatment groups, each group 10 repeats, each repeats 200.
[0041] Experimental group: The feeding method was mixed feeding with basic full-price feed + 0.30% mass percentage of basic full-price feed for laying hens.
[0042] Control group: The feeding method was the basic complete price feed. The experiment was carried out at the Shihe Base of Sichuan Shengdi Le Village Ecological Food Co., Ltd.
